Hello! I have kernel version 4.1.10-bone16 with the same issue as pbft. I tried following the "Compatibility issues section". I did the following and rebooted:

What am I missing here? My final objective is actually to disable the HDMI to use the pins for the PRU. Thank you very much for the help! It is quite impressive that almost every post I see about beaglebone I see the name Robert Nelson.
